Recombinant StaphylococcalProtein Ais a cell wall protein deriving from Staphylococcus aureus which exhibits unique binding properties for IgG from a variety of mammalian species and for some IgM and IgA as well. It binds with the Fc region of immunoglobulins preferentially through interaction with the heavy chain. It is conjugated to a wide variety of reporter molecules including fluorescent dyes, enzyme markers, biotin, colloidal gold and radioactive iodine for use in immunology and other biological researchwithout affecting the antibody binding site.Itis also immobilized onto solid supports such as agarose beads for total IgG purifying from ascitic fluid, serum,culture supernatantsand cell extract or interest protein.

Antibody purification proteinsare specialized tools designed for the specific capture and purification of antibodies from complex biological samples. In biopharmaceuticals, diagnostic reagent development, and scientific research, efficient and reliable antibody purification is a critical step to ensure the quality and functionality of antibodies.
